The problem with Ethereum is the same as early-releases in gaming.

Ethereum kept being bought for real money, and pumped into projects with nothing but a whitepaper. Allowing small teams acquire cash before they actually have to prove something, or provide a service. Now we have billion dollar projects with absolutely nothing to show for it. The market cap has become insanely high, and with the much smaller amount of actual money in the ecosystem getting pulled out at the moment the house of card is falling. Anything that is just an ERC-20 token shouldn’t be worth more than a couple of millions, at this point.No crypto has proved its viability except Bitcoin as a main trading pair, and Monero as a fungible private currency, which is why they’re the ones taking the least hit.We gave billions of real cash to prop up some worthless tokens which are now going to the shitter with Ethereum, because the ponzi scheme it created is falling. No one is investing in ICOs with ETH in this time, so it can’t be propped up to an unreasonable price.EDIT:To the people who seem to be confused: scalability is not what I’m concerned about. I don’t think anyone is. But the mentality of releasing products that are at best a demo, and at worst a text on a random .io website, and them suddenly being worth billions is the problem. Ethereum only went up because of it being in high demand for ICOs and becoming more scarce as the teams held on to the ETH. These days no one with any common sense would touch an ICO, and there is no demand for ETH. That combined with the scared ICO teams selling their ETH will make the trend go downward. My standpoint is that ICOs are scammy in nature, and will hopefully be purged. If they are purged there is no demand for Ethereum outside of dApps and those make up a miniscule use for Ethereum. If you agree that ICOs should continue to be valuated at billions, like EOS, Cardano and Tron and that the market will go up again in a frenzy of worthless products, then Ethereum is a good bet. If you think that crypto will start seeing through the scams, and that real fungible blockchain projects that have been in development for years will be the biggest gainers on the next up-turn, then Ethereum is a bad bet.
